Area and Perimeter Practice Test 3

Suppose length and breadth of the rectangular field are 11x m and 8x m.
∴ Perimeter of the field = 2(11x + 8x) = 2 × 19x = 38x m.
Now, 38x = 760 ⇒ x =

760

38

= 20
∴ Length of the field = 11 × 20 = 220 m
Breadth of the field = 8 × 20 = 160 m
∴ Area of the field = 220 × 160 = 35200 sq. m.
