Question

length of a rectangle exist in breadth by 4m. If the perimeter of rectangle is 84 m find the length and breadth. ​

Answer 1

Answer:

length=38

breadth=4

Step-by-step explanation:

breadth=4

84-4-4=76

2 length=76

1 length=38

Answer 2

SOLUTION

Length = x

Length = xbreadth= x+4

Perimeter of rectangle= 84m (given)

A/q

A/qPerimeter= 2(l+b)

A/qPerimeter= 2(l+b)=)2(x+x+4)= 84m

=) 2(2x+4)= 84m

=) 4x+8= 84m

=) 4x= 84-8

=) 4x= 76

=) x= 76/4

=) x= 19m

So,

Length= 19m

breadth, x+4 = 19+4= 23m

hope it helps ☺️
