Question

perimeter of a square, whose area is 144cm² , is
Answer is 50 cm
give solution​

Answer 1

Answer:

AREA OF SQUARE: S×S

144=s²

s²=√144

   =12

∴1 side is 12cm

If 1 side is 12cm then the perimeter= 4s

                                                            = 4×12

                                                            =48

(S DENOTES SIDE)

area of square is s×s (SIDE=S)

area of rectangle is l×b (L= LENGTH ; B=BREADTH)

area of parallelogram=b×h (B=BASE ; H=HEIGHT)

area of triangle= 1/2 ×b×h (B=BASE ; H=HEIGHT)

area of circle= πr² (R=RADIUS)
