Answer 1

Answer:

$\huge{\underline{\color{teal}{\textsf{\textbf{~~~Answer}}}}}$

Given :-

• length is 4 times of breadth

• perimeter is 90m

Solution :-

let the breadth be x

so the length will be 4x

we know that perimeter of rectangle is = 2(length + breadth )

→ 90m = 2 ( x + 4x )

→ $\frac{90}{2}$ = 5x

→ 45m = 5x

→ x = $\frac{45}{5}$

→ x = 9

thus, length is 4 × 9 = 36m and breadth is 9m

Answer 2

Given :

• Length of rectangle = 4(Breadth of rectangle)
• Perimeter of rectangle = 90m

To find :

• Dimensions of rectangle

Explaination :

• Let breadth of the rectangle be x.
• Let length of rectangle be 4x.
• Perimeter of rectangle = 2(l+b)
• So, the equation goes like this :
• 2(4x+x)=90m
• 2(5x)=90m
• 10x=90m
• x=9m
• Therefore, breadth = 9m ; length = 36m
