Question

the length and the breadth of a rectangle are (4x-7) cm and (3x+5) cm. if the value of x is 2, what is the perimeter of the rectangle?​

Answer 1

Answer:

24

Step-by-step explanation:

If x=2,

Length = [4(2)-7] and Breadth = [3(2)+5]

Perimeter = 2*{ [4(2)-7]+[3(2)+5] }

                 = 2*(1+11)

                 =2*12

                 =24

Answer 2

b=4x-7=4×2-7=1cm

l=3x+5=3×2+5=11cm perimeter of rect.=2 (l+b)=2 (1+11) perimeter of rect.=24cm^2
