Dear maths guru,

Need help!!

Area of triangle problem.
1) The area of the triangle is 1/16 of the area of the rectangle. If the total area of the rectangle and triangle is 252 cm2. Find the perimeter of the rectangle.



Thanks[/quote]The answer is 60cm
This is what her's correction from teacher:

7U : 252 cm2
1U:252/7 = 36cm2
area of rectangle: 6x36cm2 = 216 cm2
L of the rectangle: 216 / 12 = 18 cm
perimeter of rectangle : 2(L+B) = 2(18+12)
= 60 cm.

But I do not know why 7U comes from...???

Thanks
Daddy :stupid:
