2. Rectangle------->Formula:
A=length x width
Length= 5cm =
Width= 3cm

3. Triangle------->Formula:
A=0.5x base x height
= 0.5x
A.Base = 3cm
Height = 2cm

B.Base = 4cm
Height = 1cm

C.Base = 4cm
Height = 3cm​


Sagot :

2. Rectangle (A = l × w)

Length = 5cm ; Width = 3cm

A = 5cm × 3cm

A = 15

3. Triangle (A = ½ × base × height)

Base = 3cm ; Height = 2cm

A = ½ × 3cm × 2cm

A = 3

Base = 4cm ; Height = 1cm

A = ½ × 4cm × 1cm

A = 2

Base = 4cm ; Height = 3cm

A = ½ × 4cm × 3cm

A = 6
