Question

The perimeter of a rectangular grassy plot is 189m and width is 10.5m.Find The length and area

Answer 1

Answer:

Length is 84m

Area is 882m2

Step-by-step explanation:

Length=x

Length==

Perimeter=2(l+b)

189=2(x+10.5)

189=2x+21

189-21=2x

168=2x

168÷2=x

84=x

Area=lxb

=84x10.5sq.m

=882sq.m

Answer 2

Given : Perimeter of rectangular grassy plot = 189m

Breadth (width) = 10.5m


To find : Area and Length of the plot


$\boxed{\boxed{\tt{Solution :- }}}$

By using the formula of Perimeter, we will find the length.

Perimeter = 2(length + breadth)

☛ 189 = 2(length + 10.5)

☛ 189 = 2length + 21

☛ 189 - 21 = 2length

☛ 168 = 2length

∴ $\pink{\underline{\pink{\underline{\tt{\red{Length\:=\:84m}}}}}}$


Now, we will find area of the plot by using the formula :-

Area of rectangle = length × breadth

☛ 84m × 10.5m

∴ $\pink{\underline{\pink{\underline{\tt{\red{Area\:of\:rectangular\:plot\:=\:882m^2}}}}}}$
