Question

Find the perimeter of a rectangle whose:
2. 7
Area = 8----sq mm, length =5-----mm
3. 9
Show whole method/solution how to find it.

Answer 1

p= l+b
p=5+x
5-8=b
b=3
p=l+b
p=5+3
=8

Answer 2

Area=l×b       8=5×b b     =8/5mm Therefore perimeter=2(5+8/5)          =2{(25+8)/5}           =2×33/5  Solve you get the answer
