Answer:
2(W + 6) + 2W = 90 where W = the width.
Step-by-step explanation:
The perimeter is 2L + 2W where L = the length and W = the width of the rectangle.
The length L = W + 6 so the equation is:
2(W + 6) + 2W = 90.
Answer:
2(w+6)+2w=90
Step-by-step explanation:
let l is the length of rectangle and w is the width of rectangle.
Perimeter of rectangle is 2(l+w).
so, P=2l+2w
From question statement, we observe that
A rectangle is 6cm longer than its wide and perimeter is 90 cm.
P=90 cm and l= w+6
P=2l+2w
putting the value of P and length,we get
90=2(w+6)+2w
rearranging above equation,we get
2(w+6)+2w=90
