Calculate the area of this trapezium

= 72 cm²

Step-by-step explanation:

A = (b + B)×h/2

= (9cm + 15cm)×6cm/2

= 24cm×3cm

= 72 cm²

72 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 6 , a = 15, b = 9 , thus

A = × 6 × (15 + 9) = 3 × 24 = 72 cm²

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
