Question

A rectangle is having length (x+4)cm and breadth (x+6)cm.

Find its (i) Perimeter (ii) Area
​

Answer 1

Step-by-step explanation:

Let the breadth of the rectangle be x cm.

Then its length is x+4 cm.

According to the problem,

2{x+x+4}=36

or, 2x+4=18

or, x=7.

So breadth of the rectangle is 7 cm and length is 11 cm.

So the area of the rectangle is 7×11=77 cm

Answer 2

Answer:

Hope this helps you

Step-by-step explanation:

length= (x+4) cm

breadth= (x+6) cm

(I) Perimeter

= 2(l+b)

= 2( x+4 + x+6)

= 2( 2x +10)

= 4x + 20

(ii) Area

= l(b)

= (x+4)(x+6)

= x(x+6) + 4(x+6)

= x² + 6x + 4x + 24

= x² + 10x +24
