Answer 1

Please complete your question

These are the basic area formulas

triangle

Area = ½ × b × h

b = base

h = vertical height square Square

Area = a2

a = length of side

rectangle Rectangle

Area = w × h

w = width

h = height parallelogram Parallelogram

Area = b × h

b = base

h = vertical height

trapezoid Trapezoid (US)

Trapezium (UK)

Area = ½(a+b) × h

h = vertical height circle Circle

Area = π × r2

Circumference = 2 × π × r

r = radius

ellipse Ellipse

Area = πab

sector Sector

Area = ½ × r2 × θ

r = radius

θ = angle in radians

Note: h is at right angles to b: altitude
