Question

Calculate the area of the shaded portion in fig 19.54 and fig 19.55.
Plz help and solve this question God for sake

Answer 1

19.55

ar(∆ABC)=50/2=25

ar(Rectangle + Square)=18×10+6×6 =180+36=216

ar(∆FED)=24/2=12

Total area of shaded part is =216+12+25=253 cm square

19.54

ar(ABE)=12÷2=6

ar(BED)=12÷2=6

Total area =12cm square

Area of ∆ =

$1 \div 2 \times base \times height$

Area of rectangle =length × breadth

Area of square =side ×side
