Question

the perimeter of a square is equal to the perimeter of rectangle of length 30 cm the area of triangle is 360 cm what is the side of the square​

Answer 1

Answer:

how area of triangle can be 360cm

/????

Step-by-step explanation:

Answer 2

Area =length *breadth

Putting value of area and length ( given)

360=30*breadth

Now, taking 30 to the left side of equal sign. So we get, 360/30=breadth

Breadth =12

Now we got breadth and we have already the length of rectangle

So perimeter of rectangle =2(l+b)

perimeter of rectangle =2(l+b) =2 ( 30+12)

perimeter of rectangle =2(l+b) =2 ( 30+12) =2*42=84

So perimieter of rectangle = perimeter of square ( given in question)

So, side of square = 84/4

= 21 ans
