Answer 1

Answer:

1. Area of the Triangle = 306cm²

Area of the Triangle = 1 / 2 × b × h

A = 1 / 2 × b × 18

306 = b × 9

b = 306 / 9

b = 34cm

Hence ;

Base of the Triangle ( b ) = 34cm

2. Area of the Parallelogram = 25.48cm

Height of the Parallelogram = 4.9m

Area of the Parallelogram ( A ) = b × h

A = b × 4.9

25.48 = b × 4.9

b = 25.48 / 4.9

b = 5.2cm

Hence ;

Base of the Parallelogram ( b ) = 5.2cm

3. 1 hectare = 10000Sq.meters

Area of the Parallelogram = 2 hectares

Base of the Parallelogram ( b ) = 250m

= 0.025 hectares

Area of the Parallelogram = b × h

A = 0.025 × h

2 = 0.025 × h

h = 2 / 0.025

h = 80 hectares

Or ;

Convert into meters

Area of the Parallelogram = 2 Hectares

= 20,000 m²

Base of the Parallelogram = 250m

Area of the Parallelogram = b × h

A = 250 × h

20000 = 250 × h

h = 20000 / 250

h = 80 m
