Question

Find the missing value base =? height = 17 mm area =221 mm2​

Answer 1

Answer:

area of triangle : 1/2 * base * height

Step-by-step explanation:

221mm2= 1/2 * base * 17mm

221mm2=base * 8.5

221mm/base = 8.5mm 2

221mm /base =2.91mm

221mm= 2.91mm * base

221mm /2.91mm = base

75.94mm = base

Answer 2

Step-by-step explanation:

given,

Base=?, Height=17mm, Area=221mm^2

base=b

height=h=17mm

Now,

Area of parallelogram=b×h

221=b×17

221/17=b

b=13
