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
