The length and breadth of a rectangular plot are in the ratio 9:5. If its
perimeter is 280, find area.
Answers
Answer:
4500 m^2
Step-by-step explanation:
Let x be the ratio
= 9x : 5x
Now with this value we can find x by finding the perimeter
Perimeter = 2(Length + breadth)
280 = 2( 9x + 5x)
280 = 2(14x)
280 = 28x
x = 10
now that we have x lets substitute
Length = 9*10 = 90 m
Breadth = 5*10 = 50 m
Now that we have the original values of length and breadth we can find the area by using the formula
Area = L x B
Area = 90 x 50 = 4500 m^2
Answer:
4500 m2
Step-by-step explanation:
given
length = 9x
breadth = 5x
perimeter = 280m
so,
perimeter formula => 2( l + b )
=> 2( 9x + 5x )
=> 2( 14x )
=> 28x
28x = 280
x = 280/28
x = 10
length = 9x => 9 * 10 => 90m
breadth = 5x => 5*10 => 50m
area of a rectangle = length * breadth
= 90x * 50x
= 4500m2
