Question

please give answers with solutions ​

Answer 1

(1) L=5m

b=?

area =15m²

find the perimeter and breadth

area of rectangle=l×b

15=5×b

b=15/5

b=3m

perimeter of rectangle=2(l+b)

=2(5+3)

=2(8)

= 16m²

(3)L=?

b=9.5cm

perimeter=24cm

find the area and length

perimeter of rectangle= 2(l+b)

24= 2(l+9.5)

24=2l+19

24-19=2l

5=2l

l=5/2

l= 2.5

area of rectangle=l×b

=2.5×9.5

=23.75
