Question

the length of the rectangle is 3/4 of its breadth if the perimeter is 126 M then its area will be

Answer 1

length /breadth = 3/4

perimeter = 2( l+ b)

= 2 ( 3x + 4x)

= 14x

14 x = 126

x = 9 then

length= 27

breadth = 36

area = length * breadth

area = 27 * 36

area = 972

Answer 2

Answer:

Step-by-step explanation:

Breadth=b

Length=3/4*b

Perimeter=2(l+b)

126=2(3/4*b+b)

126=2*3/4b+2b

126=3/2b+2b

(find Lcm)

126=7b/2

126*2=7b

252=7b

252/7=b

B=36

Breadth=36

Length=3/4 * 36=27

Area=l*b

=36*27

=972 Sq m
