Answer 1

Answer:

Option d is correct. Hope it helps!

Answer 2

Answer:

Answer is

Step-by-step explanation:

Perimeter of the square=48 cm

Side of the square will be 48/4 as the perimeter of sq. is 4×side= 12 cm.

Area of the square=side×side

=12 cm×12 cm

=12 cm²

=144cm²

Area of triangle=4 cm less than the square area

Area of the triangle=144 cm-4

=140 cm²

Base of the triangle=14 cm

Area of triangle= base×height

140 cm²= 1/2 × 14×height

140 × 2/14= height

Therefore height= 20 cm

You can check it too.

By multiplying. Lets see:-

1/2 × Base × Height = Area

1/2 × 14 cm × 20 cm = 140 cm²
