Math Area of Polygons I

Reminder - Area is the space taken up inside a shape. Area is measured in square units. Perimeter is the measure around the outside of a shape. This is an Area quiz. On lined shapes, you can just count the squares inside. 4cm The formula for area is Length x width 3cm 7cm 14cm 12cm 28cm 2 2 2 2 2yds Area of a rectangle is Legnth x width 8yds 10yds ^{2}24yds 16yds ^{2}8yds ^{2}If you know the area is length x width, you can find the unknown side by dividing. You can also plug in the numbers. ? A = 40ft ^{2}5 ft The unknown side is 10 ft 8 ft 1 ft 4 ft 5 x ? = 40 40 ÷5 =? 4mm 40mm 8mm 16mm What is the unknow side? A=80mm ^{2}? 20 mm 3cm Area of this shape is? 9cm 24cm ^{2}27cm ^{2}12cm ^{2}57cm ^{2}This is a square. You can find area by knowing just one side since all sides are equal. 4mm The formula is side times itself A= 16m ^{2}4m 4mm 4mm 4 x 4 5m What is the area of this square? 20m ^{2}10m ^{2}15m ^{2}25m ^{2}A=36in ^{2}What is the measure of each side of this square? 6in 18in 12in 10in The formula for the area of a 2 Drag the answers to the right spot Area ? = 6 units ^{2}Lenght ? X Width Type the area of the shape. rectangle ? is: |
