Area and Perimeter Practice Test 2

Question : 33 of 40

Marks: +1, -0

The difference between the length and breadth of a rectangle is 23 m. If its perimeter is 206m, then its area is:

Solution:

Here, l – b = 23 ...(i)
and also, 2 (l + b) = 206
∴ l + b = 103 ...(ii)
Hence, l =

1/2

(103 + 23) = 63 m
b =

1/2

(103 - 23) = 40 m
Since, A = 63 × 40 = 2520

m^2
