Question

PQRS is a parallelogram. PO and RT are the perpendiculars on the sides RS = 30 cm and PS == 20 cm and the area of parallelogram is 300 cm. Find the length of PO and RT. 7Q PR T 20 cm R O 30 cm​

Answer 1

Answer:

Area of parallelogram = 300cm^2

length of RS=30

" " " PS=20cm

so

Base×Height= parallelogram

To find PO

Base×height = Area (Base=RS, Height = PO)

$30cm \times h = {300cm}^{2} \\ \\ h = \frac{ { \cancel{300}} \: \: ^{10} }{ \cancel{30}} \\ \\ h = 10cm$

So

PO=10cm

$\rule{200pt}{5pt}$

To find RT,

Base×Height=Area (Base=PS, Height=RT)

$20cm \times h = {300cm}^{2} \\ \\ h = \frac{ { \cancel{300}} \: \: ^{15} }{ \cancel{20}} \\ \\ h = 15cm$

So

RT=15cm

PO=10cm

RT=15cm

Answer:

A lot rides on the opening lines of a short story. You'll want to strike the right tone, introduce the characters, and capture the reader's attention all at once — and you need to do it quickly because you don't have many words to work with!
