Question

Please help with this 7th grade math I need to pass this test

Answer 1

Area of triangle = (1/2) × Base × Height

Area of bigger triangle = (1/2) × 15 cm × 10 cm

Area of bigger triangle = (1/2) × 150 sq. cm

Area of bigger triangle = 75 sq. cm

Similarly,

Area of smaller triangle = (1/2) × 12 cm × 5 cm

Area of smaller triangle = (1/2) × 60 sq. cm

Area of smaller triangle = 30 sq. cm

Area of shaded region = Area of bigger triangle - Area of smaller triangle

Area of shaded region = 75 sq. cm - 30 sq. cm

Area of shaded region = 45 sq. cm

Answer :

Area of shaded region in sq. cm = 45

Answer 2

Answer is 45

Step by step exploration
A=10*15/2-5*12/2=75-30=45
