Question

24. From the following figure, find the value of a.​

Answer 1

Answer:

2(l+b)

2*(4a+3+2a+1)=10+1

8a+6+4a+2=11

12a+8=11

12a=11-8

12a=3

a=3/12

a=1/4

Answer 2

it is a rectangle so its given perimeter is (10+1)cm

we know that perimeter = 2(l + b)

perimeter = 2(4a+3+2a+1)

=2(6a+3)

=12a+6

we can say that 12a+6=10+1

=12a= 11-6

=12a=5

=a=5/12
