Answer 1

Answer:

ques 1:2(l+b) = p

P=2(5+b)

10+2b=18

b=18-10/2

b=4

ques 2: usage of 1/2 *b *h (area of triangle)

13=base

12 = height

1/2* 13*12=78 cmsq

area of rectangle = 78 x2

156 cmsq

ques 3:

area of rectangle - area of triangle

960 cmsq - 180 cmsq = 780 cmsq.

ques 4:

area = base * height

height = 60/12.5=4.8 cm sq

ques 5:

side of square = 30

area = 30x 30= 900

h of ||gm=

900/15

=60 cmsq.

ques 6:

same

area of square=30 x30 = 900

base of triangle = 900/90 = 10
