A rectangle shows a length labeled 6 centimeters and a width labeled 3 centimeters.
Jacinda draws a rectangle with measurements 6 cm and 3 cm. What is the area of the rectangle in square centimeters?
To find the area of a rectangle, you multiply the length by the width.
6 cm x 3 cm = 18 square centimeters
Therefore, the area of the rectangle is 18 square centimeters.
A traffic sign is in the shape of a square with each side equal to 20 inches. What is the area of the sign in square inches?
To find the area of a square, you square the length of one of the sides.
20 inches x 20 inches = 400 square inches
Therefore, the area of the square traffic sign is 400 square inches.
Students in a summer art class paint a rectangular mural. The shorter side of the mural measures 5 yards. The longer side measures 3 yards longer than the shorter side. How many square yards is the mural's area?
Given:
Shorter side of the mural = 5 yards
Longer side of the mural = 5 + 3 = 8 yards
To find the area of the mural, we multiply the length by the width:
Area = Length x Width
Area = 5 yards x 8 yards
Area = 40 square yards
Therefore, the area of the mural is 40 square yards.

An illustration shows an obtuse triangle with a base of 9 centimeters. The perpendicular height on the right is marked by a dashed line drawn from the top vertex to an extended dashed line from the base labeled as 7 centimeters. A right angle symbol is shown where the base and height meet at the dashed lines.
What is the area in square centimeters of the triangle pictured here?
To find the area of a triangle, we use the formula:
Area = 1/2 x base x height
In this case, the base of the triangle is given as 9 centimeters and the height is given as 7 centimeters.
Area = 1/2 x 9 cm x 7 cm
Area = 1/2 x 63 cm
Area = 31.5 square centimeters
Therefore, the area of the triangle in the picture is 31.5 square centimeters.
Farah cuts a sheet of paper into the shape of a triangle. The triangle has a height of 6 inches and a base of 7 inches. What is the area of the triangle in square inches?
To find the area of a triangle, we use the formula:
Area = 1/2 x base x height
Given:
Base = 7 inches
Height = 6 inches
Plugging in the values:
Area = 1/2 x 7 inches x 6 inches
Area = 1/2 x 42 square inches
Area = 21 square inches
Therefore, the area of the triangle is 21 square inches.
