you only need 2 things to find the area of the triangle, base and height. The formula for finding the area is 1/2(base x height)
if we plug the numbers we are given into the formula we find
1/2(7x8)
1/2(56)
28

Answer:
(B) 18 cm x 8 cm
Step-by-step explanation:
let the length be x,
then the width is 
x + 2
2( x + 2 + x ) = 52
x + 2 + x = 26
= 24
x = (24*3)/4
x = 18
then the length is 18 cm
and width is (1/3)*18 + 2 = 8
Therefore the dimensions are length:width = 18 cm : 8 cm

Answer:
l = 6.00
Step-by-step explanation:
So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so
3l = 2l + 2(3), so l = 6.
