| A rectangle has the width of 44 centimeters and a
perimeter of 188 centimeters? what is the rectangles length?
|
ANSWER:
|
You already know that if L is the length of the rectangle and W its width then its Perimeter is given by : P = 2( L + W ) ......................( 1 ) Now : W = 44 and P = 188 according to your given. Substituting these values in ( 1 ) : 188 = 2( L + 44 ) 188 = 2L + 2(44) 188 = 2L + 88 188 - 88 = 2L i.e , 2L = 100 Dividing both sides by 2 : L = 50 cm Checking : W = 44 and L = 50 : P = 2 ( L + W ) = 2 ( 50 + 44 ) = 2 ( 94 ) = 188
