Answer:
150 cm²
Step-by-step explanation:
the way is we will find out the area of square and the 3 triangles inside the square.Then we will subtract the sum of the areas of triangles from the area of square which will give us the area of the shaded portion .
area of square = 20 × 20 = 400cm²
area of 3 triangles = 100cm²+ 100cm² + 50 cm²=250 cm²
and finally 400 - 250 = 150 cm²
Now
Area of shaded portion
Area of PQRS-Area of triangle PQT -Area of triangle STU-Area of triangleQRU
400-100-50-100
400-(100+50+100)
400-250
150 cm²
