Answer:
Length=23
Breadth=4
Step-by-step explanation:
Let the breadth be x
then the length will be 4x+7
Perimeter=54
2(l+b)=54
2(x+4x+7)=54
2(5x+7)=54
10x+14=54
10x=40
x=4
Question :-
the length of a rectangle is 7 more than 4 times of its breadth find the dimensions of the rectangle if its perimeter is 54cm
Answer :-
let the breadth of the rectangle be x cm
then length of the rectangle is 7 + 4x cm
and we know that,
so, breadth of the rectangle is 4cm
then, length = 7 + 4 × 4 = 23cm
hence, length and breadth of the rectangle are 4cm and 23cm respectively
