Question

The perimeter of a rectangle is 84 m. if its breath is 17 m, find its length​

Answer 1

Answer:

25cm

Step-by-step explanation:

perimeter of a rectangle= 2(l+b)

so, 2(l+17)=84

(l+17)=84/2

therefore,(l+17)=42

l=42-17

then length is 25cm.

Answer 2

Question

• Perimeter of rectangle is 84m, Breadth is 17m.

To find

• We have to find the Length of the rectangle.

Answer

$\underline{\bf \gray{\dag}\:\mathfrak{as \ we\ know: :}}$

$\;\boxed{\sf{\purple{perimeter_{\:(rectangle)} = 2 \times (Length + Breadth)}}}$

$\sf \green{breadth} \sf \rightarrow \sf \blue{17_{\:(m)}}$

$\sf \pink{length} \rightarrow x$

$\sf\red{Perimeter}$ = $\sf{\dfrac{{\cancel 84}}{{\cancel 2}}}$ = 42

$\sf{Perimeter = Perimeter \div 2 - Breadth}$

$\sf{Perimeter = 42m - 17m \rightarrow 25m}$

∴ Hence, verified! that the Length is 25m.
