Question

if the perimeter of a rectangle is 138 metres and the difference between the length and the breadth is 7 metres. What is the area of the rectangle​

Answer 1

Answer:

1178

Step-by-step explanation:

P=138m

l-b=7, l=7+b

Perimeter of rectangle=2(l+b)

138=2(7+b+b)

138=2(7+2b)

7+2b=69

2b=62

b=31

l=7+b

so,l=7+31=38m

Area=lxb

=38×31=1178
