Sumathi says that the area of a triangle PQR is, A=1/2×8×7 CM. rajini says that it is A=1/2×9×7 cm. who is correct? give reason?

please answer me fast!!!

Rajini is correct, A = 1/2 × 9 × 7

Step-by-step explanation:

A = 1/2 × base × height

base = the leg bisected by the height, in this case leg QD = 9cm

height = 7cm in this case

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
