Answer:

96 inch²

Step-by-step explanation:

there are 2 shapes,

1. a square

2. a triangle

lets find the area of the square first,

<u>AREA = SIDE × SIDE</u>

= 8 × 8

= 64 inch²

now, area of triangle ,

$area \: = \frac{1}{2} \times base \: \times height \:$

$= \frac{1}{2} \times 8 \times 8 \\ = \frac{1}{2} \times 64 \\ = 32 \: {inch}^{2}$

so, total area is :

area of square + area of triangle

= 64 + 32

= 96 inch²

If xsquared+ysquared=57 , xy=3 . find the value of 3(x+y)squared

shepuryov [24]

Answer:

189

Step-by-step explanation:

If you mean this, my answer is 3x63= 189

${x}^{2} + {y}^{2} = 57 \\ xy = 3$

${x}^{2} + {y}^{2} + 2xy = 57 + 2 \times 3$

${(x + y)}^{2} = 63$

$3 {(x + y)}^{2} = 3 \times 63 = 189$
