Question

HELP PLS MIGHT GIVE BRAINLIST BUT ONLY IF 2 PEOPLE ANSWER!

Answer 1

Answer:

$(21in,30in)=>210in^2$

$(15in,18in)=>90in^2$

$(15in,30in)=>150in^2$

Step-by-step explanation:

Required

Match the expressions on the left with the right

(a) 21 in by 15 in

Calculate area

$Area = 21in * 15in$

$Area = 315in^2$

Multiply by $1/3$

$1-third = 315in^2 * \frac{1}{3}$

$1-third = 105in^2$

Hence:

$(21in,15in)=>105in^2$

(b) 21 in by 30 in

Calculate area

$Area = 21in * 30in$

$Area = 630in^2$

Multiply by $1/3$

$1-third = 630in^2 * \frac{1}{3}$

$1-third = 210in^2$

Hence:

$(21in,30in)=>210in^2$

(c) 15 in by 18 in

Calculate area

$Area = 15in * 18in$

$Area = 270in^2$

Multiply by $1/3$

$1-third = 270in^2 * \frac{1}{3}$

$1-third = 90in^2$

Hence:

$(15in,18in)=>90in^2$

(d) 15 in by 30 in

Calculate area

$Area = 15in * 30in$

$Area = 450in^2$

Multiply by $1/3$

$1-third = 450in^2 * \frac{1}{3}$

$1-third = 150in^2$

Hence:

$(15in,30in)=>150in^2$
