Question

the perimeter of a rectangle is 42m and it's breadth is 7.4m.find the length and the area of the rectangle

Answer 1

HI there,

Here is your answer :
____________________________

Given,

Perimeter of rectangle = 42m

Breadth of rectangle = 7.4m

Perimeter of rectangle = 2(l+b)

ATP,

42 = 2( l + 7.4)

42 /2 = ( l +7.4)

21 = l + 7.4

21-7.4= l

l = 13.6m

Area of rectangle = l * b

= 7.4*13.6

= 100.64
