The perimeter of rectangle ABCD is 256 inches. It's length is 3 times as long as its width. Find the area of triangle ABC.
Answered by Reiny
width --- x
length --- 3x

2(x+3x) = 256
8x = 256
x = 32

width = 32
length = 96
Area = 32(96) = 3072

P= 2(L+B)
258= 2( 3x + 1x)
258= 2 ( 4x )
258= 8
43*3
86cm 258 1/2 6
43cm
A= B*H 1/2
= 43* 86 1/2
=3698cm 1/2 = 1849 cm2
