Question

The+area+of+a+rectangle+is+540cm2and+its+length+is+36+cm+.Find+its+width+and+perimeter+answer+in+detail+subject+math

Answer 1

area of rectangle = l*b
l=36
and area=540
therefore

540=36*b
b=540/36
=15

perimeter of rectangle = 2*(l+b)
= 2*(36+15)
=2*51
=102

Answer 2

Given
Area =540cm²
Length =36cm
Width =?

Area of rectangle =lxb
36xb=540
$b = \frac{540}{36}$
b=15cm

Area of rectangle=2(l+b)
=2(36+15)
=2(51)
102cm
