Step-by-step explanation:

The first figure is a parallelogram with area (A) calculate as

A = bh ( b is the base and h the perpendicular height )

Here A = 144, b = 16 and h = x, thus

144 = 16x ( divide both sides by 16 )

x = 9

----------------------------------------------------------

The second figure is a trapezium with area (A ) calculated as

A = h (a + b)

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

Here A = 480, h = x, a = 37 and b = 27, thus

480 = x (37 + 27) = x × 64 = 32x ( divide both sides by 32 )

x = 15

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
