Question

OPQRS is a rectangle. If PQ = 14 cm, QR = 21 cm,
Find : (i) Area of the part x
TIRL​

Answer 1

Answer:

part x(area under PQT) = it is the part of a circle and PQT is one-forth(1/4) of circle hence

PQ and QT is the radius of circle

area of the PQT = π r²

area of the PQT = 3.14 × (14)²

area of the PQT = 3.14 × 196

area of the PQT = 615.44 cm²
