Question

The difference between the length and breadth of a rectangle is 6 m. If its perimeter is 64 m, then its area is:
A. 256 sq.m
B. 247 sq.m
C. 264 sq.m
D. 238 sq.m​

Answer 1

Answer:

247sq. m

Step-by-step explanation:

247sq. m is the area of rectangle

Answer 2

Answer:

Given that, l-b =6m......(1)

And,. Perimeter(P)=2(l+b)=64m....(2)

Area= lxb

From (2),(l+b)=32......(3)

Solving 1 and 3 we get,

2l=38

Therefore, l=19m

Now from (1), b =13m

Therefore, A=19×13=247m^2.
