Answer 2

Answer:

$4900 {cm}^{2}$

Step-by-step explanation:

Given:-

perimeter of sqr. photo frame = 280 cm

To find:-

area of this sqr.

Solution:-

perimeter of square = 4×side

let side of square be 'x' cm

then,

perimeter=

$4 \times x = 280$

$x = \frac{280}{4} \\ x = 70$

Hence, Side of given square = 70 cm

Now, finding its area:-

Area of square= side×side

then,

area=

$70 \times 70 \\ 4900 {cm}^{2}$

Hence, The area of square photo frame=

$4900 {cm}^{2}$
