The figure is made up of a rectangle and a triangle. Find the perimeter in cm.
Perimeter = 6 + 7 + 3 + 5 + 11 = 32 cm
4 squares, each of side 3 cm, are cut from a rectangle 25 cm by 16 cm as shown. Find the area in centimeter squares.
Area = (25 x 16) - (4 x 3 x 3) = 400 - 36 = 364 Centimeter square.
The figure is made up of 4 identical rectangles, each measuring 8 cm by 5 cm. Find the perimeter in centimeter !
Perimeter = (4 x 8) + (4 x 5) + (4 x 3) = 32 + 20 + 12 = 64 cm
The figure is made up of 4 identical rectangles, each measuring 8 cm by 5 cm. Find the area in centimeter squares.
Area = 4 x (8 cm x 5 cm) = 160 centimeter squares
The figure is made up of two squares. Find the area in centimeter squares.
Area = (8x8)+(5x5) = 64 + 25 = 89 centimeter squares.
The figure is made up of two squares. Find the perimeter in centimeter !
Perimeter = 8 + 8 + 3 + 5 + 5 + 13 = 42 cm
4 squares, each of side 3 cm, are cut from a rectangle 25 cm by 16 cm as shown. Find the perimeter in centimeter
Perimeter = (2 x 25) + (2 x 16) = 50 + 32 = 82 cm
The figure is made up of a rectangle and a triangle. Find the area in centimeter squares.
Area = (7 x 6) + (1/2 x 4 x 3) = 42 + 6 = 48 centimeter squares.
