Question

the area of trapezium is 273 cm² the length of its parellel sides are 10 cm and 16 cm find the altitude ​

Answer 1

Answer:

area of trapezium=1/2 (a +b) *h

273=1/2(10 +16)h

h=273*2/26

h=26

Answer 2

Answer:

Altitude = 21 cm

Step-by-step explanation:

Given,

Area of the trapezium = 273 cm²

Length of one parallel side = 10 cm

Length of anothet parallel side = 16 cm

Altitude = x

According to the question,

½ × (sum of the parallel sides) × altitude = 273 cm²

½ × (10+16) × x = 273

½ × 26× x =273

13x = 273

$x = \frac{273}{13}$

x= 21
