equal to the sum of the areas of first two squares would be:
A)18cm
B)20cm
C)28cm
D)30cm​

Answer 1

OPTION B✔️

Side of 1st square == 4 cm

Side of 2nd square == 3cm

ACCORDING TO QUESTION::

A² = A1² + A2² == 16+9

Therefore , A ( side ) = 5cm

Perimeter = 4(5) = 20 cm

Answer 2

Answer:

area =16+12

(side)²=36

side = √36

side=6cm

perimeter of square=4×side

perimeter of square=4×6

perimeter of square=24cm
