Question

please solve question 10​

Answer 1

Answer:

Step-by-step explanation:

perimeter of triangle= a+b+c/2 = 60

a+b+25 / 2 = 60

a+b = 120-25 = 95

now by Pythagoras theorem

a²+b= 25²

(a+b)² - 2ab = 625

95² -625 = 2ab

ab = 4200

now area of triaangle =1/2 * a*b

= 4200/2

2100cm²

Answer 2

Answer:

2100cm^2
