Answer 2

Answer:

31/4 cm

Step-by-step explanation:

Given : Perimeter of rectangle = 23 cm

Length of rectangle = $\sf{3 {\dfrac{3}{4}} }$ cm

= $\sf{ {\dfrac{4 × 3 + 3}{4}} }$ cm

= $\sf{ {\dfrac{15}{4}} }$ cm

As we know that,

Perimeter of rectangle = 2(length + breadth)

Putting known values, we get

→ 23 = 2( $\sf{ {\dfrac{15}{4}}}$ + breadth)

→ $\sf{ {\dfrac{23}{2}} }$ = $\sf{ {\dfrac{15}{4}}}$ + breadth

→ Breadth = $\sf{ {\dfrac{23}{2}} - {\dfrac{15}{4}} }$

→ Breadth = $\sf{ {\dfrac{23(2) - 15}{4}} }$

→ Breadth = $\sf{ {\dfrac{46 - 15}{4}} }$

→ Breadth = 31/4 cm
