two plots of land have the same perimeter one is a square of side 60 m while the other is a rectangle whose breadth is 1.5 dam which plot has the greater area and by how much
Answers
Step-by-step explanation:
square side = 60m
perimeter of a square = 4× side
= 4 × 600dm
= 2400dm
perimeter of a rectangle = 2( l +d)
= 2 ( l + 1.5)
perimeter of a rectangle = perimeter of a square
2( l+ 1.5) = 2400
l + 1.5 = 2400/ 2
l = 1200 - 1.5
l = 1198.5 dm
are of a square = side x side
= 600× 600
= 360000dm
are of a rectangle = l× d
1198.5 × 1.5
= 1797.75dm
360000- 1797.75 = 358202.25dm
