Question

find (a) the area and (b) the perimeter of the square PQRS if--

(i) PQ = QR = 20cm
(ii)PQ = QR = 1.2 cm​

Answer 1

Step-by-step explanation:

(i) PQ = QR = 20cm

area = S²

=(20)²

=400cm²

perimeter=4S

=4(20)

=80cm

(ii)PQ = QR = 1.2 cm

area=(1.2)²

=1.44cm²

perimeter=4(1.2)

=4.8cm
