Question

calculate the area of the given figure
solve the answer for second question

Answer 1

Answer:

102

Step-by-step explanation:

in ∆BOC we need to find OC

as we know BOC is a right angled triangle

(side)²+(side)²=(hypo)²

(BO)²+(OC)²=(BC)²

8²+(OC)²=17²

64+(OC)²=289

(OC)²=289-64

(OC)²=225

OC=√225

OC=15

finding area of ∆BOC

area of a ∆ =1/2*b*h

=1/2*8*15

=4*15

area of ∆BOC =60 ------------ equation 1

finding area of rectangle AOCD

area of a rectangle = 2(l+b)

= 2(6+15)

= 2(21)

area of AOCD = 42 -------equation 2

adding equation 1 and 2

area of (BOC+AOCD) = 60+42 cm²

=102
