Question

Find the perimeter of a rectangle whose area is 500 CM 2 and breadth is 20 cm
​

Answer 1

Answer:

90 cm

Step-by-step explanation:

to find the perimeter

we need to find the length

Length- area➗breadth

= 500➗20= 25

perimeter= (Length+ breadth) ❌ 2

=(25+20)❌2

45*2 = 90cm

hopefully it helps

Answer 2

$\red{ \large{A}} \orange{ \large{N}} \purple{ \large{S}} \red{ \large{W}} \orange{ \large{E}} \purple{ \large{R}} \blue{ \large{ \bold{:-}}}$

$\green{ \bold{area \: of \: rectangle}} \orange{ = }\blue{ \bold{length \times breadth}}$

$\green{ \bold{500 {cm}^{2} }} \orange{ = }\blue{ \bold{length \times 20cm}}$

$\blue{ \bold{length}} \orange{ = } \frac{ \green{ \bold{500 {cm}^{2} }}}{ \blue{ \bold{20cm}}}$

$\blue{ \bold{length}} \orange{ = } \pink{ \bold{25cm}}$
