Question

Find the area of a rectangle, if the length is( 4m + 3) and the breadth is (3m+1) and the perimeter is 50 cm ?

Answer 1

perimeter of rectangle =2×(l+b)
50cm = 2× (4m+3+3m+1)
50cm/2 = 7m+4
25cm-4=7m
21cm=7m
m= 3cm


length = 4 (3)+1=13
breadth = 3 (3)+4=13
area of rectangle= l×b
= 13×13
169cm^2

Answer 2

perimeter of rectangle =2(l+b)
according to given condition 2(4m+3+3m+1)=50.
2(7m+4)=50
14m+4=50
14m=50-4
m=46/14

just put it in eq= (4m+3)(3m+1)

you get the answer by putting value of m in eq
