Answer:
A = 140 in²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
here b = 20 and h = 14 , then
A = × 20 × 14 = 10 × 14 = 140 in²
Answer:
Step-by-step explanation:
Let the length is x, then the width is 1/4x.
<u>Find the perimeter of rectangle:</u>
- P = 2(l + w)
- P = 2(x + 1/4x) = 2x + 1/2x = 2 1/2x = 2.5x
