Question

find the area of shaded portion area of triangle inside a square​

Answer 1

Answer:

72cm²

Step-by-step explanation:

first we solve the area of square 15×12 =180then we have to find the area of three triangles 12× 6 =72×1/2=36,15×6×1/2= 45, 9×6×1/2=27

then we add the three area of triangles

36+27+45=108

then we subtract the areaof three traingles

from the square

180-108= 72
