Given:
a rectangular field with an area of 1200 m²
side PQ is divided by 4 parts by point A, B, C
To Find:
Solution:
Let PQ= l and QR= b
area of rectangle = length × breadth
1200 = l × b
as PQ divide into 4 equal part therefore AB = l/4
Area of Δ ABR = 1/2 × AB × QR ( where PQ is the height of triangle)
= 1/2 × l/4 × b
=( l × b )/8
= (
= 8
Hence, the ratio is 8:1.
