A square and a rectangular field has the same perimeters. The dimensions of rectangular field are 120m × 90m. Find out which field has the greater area.
Answers
Answer:
given perimeter of square =perimeter of rectangle
4s=2 (120+90)
4s=2 (210)
4s=420
s=420/4
s=105cm
side of square is 105cm..
Area of square:
s×s=105×105
=11025cm^2
Area of rectangle:
Length ×breadth
=120×90
=10800cm^2
There fore area of square is greater than rectangle

Answer:
the squre filed has a greater area then rectangular filed.
Step-by-step explanation:
the dimensions of rectangular filed is given as follows 120m and 90m so area of rectangular filed is
l×b(120m×90m)
=10800m²
and perimeter of rectangular filed is
2(l+b)
=2(120+90)
420m
and sqaure filed's perimeter =rectangular filed's perimeter so
420m=420m
and one side of square filed is 420÷4(because square has four equal side)=105m
area of square= side×side
=105m×105m
=11,025m²
