• Length: 7 inches

  Width: 5 inches

Area = Length x Width

The only whole numbers we can multiply together to get an area of 35 are 7 and 5.

7x5=35

7+7+5+5 also equals 24, giving us the correct perimeter.

Answer explanation

It is 3 times as long as it is wide. It is 2 feet wide, so the length is 2 x 3. So, the length is 6 feet.

Area = Length x Width, so the area of the rectangle is 6 x 2 = 12.

Ms. Johnson split the rectilinear figure into rectangles. She needs to find the area of the middle section. Which equation will give her the area of the middle section?

• 6 x 3 = 18 square inches

• 9 x 3 = 27 square inches

• 3 x 3 = 9 square inches

• 3 x 2 = 6 square inches

Answer explanation

The length and width of this part of the rectilinear figure are both 3 inches. Area = length x width, so the area of this part is 3 x 3 = 9 square inches.
