Answer 1

Answer:

Number of red squares used are 79.

Step-by-step explanation:

Given that Adam had used 84 white squares.

White squares used are 20 more than that of yellow.

Let yellow squares used = $x$

($x$ + 20) is the number of white squares used.

Also given that 15 more red than yellow

So, Number of red squares used = $x+15$

To find:

Number of red squares that Adam used.

Solution:

As per given statement:

White squares used =

$x+20=84\\\Rightarrow x=64$

$\therefore$ Number of yellow squares used, $x$ = 64

Number of red squares = $x + 15 = 64+15 =79$

So, Number of red squares used are 79.
