Question

P PQRS is rectangle. PQ = 10cm, QR = som Find the area of triangle STR 1) 25 sq.om 2) 20 sq.om 3) 24.5 sq.om 4) 22.5 sq.m S 70 Ans. O​

Answer 1

here in ∆STR,

base SR= 10 cm

height PS = 5 cm

area of ∆ = 1/2 base × height

= 1/2 × SR × Ps

. = 1/2 × 10× 5

= 25 cm²

option A is correct answer.
