-Dominant- [34]3 years ago

Answer:

x = 7/\sqrt{2} or 4.949747468

Step-by-step explanation:

45-45-90 triangles have a specific pattern.

The smaller sides are x, & the hypotenuse is x*\sqrt{2}

With this knowledge, we know we have to divide the hypotenuse by \sqrt{2} to get the smaller sides, so we divide 7 by the \sqrt{2} to find x.

lora16 [44]

Answer:

875cm^2

Step-by-step explanation:

since opposite sides are equal

3x-y=2x+y

x=2y                                                      

y=x/2                                                                      ....(i)

thus new length=2x+y

=2x+(x/2)                                                              [using (i)]

=(4x+x)/2

l=5x/2                                                                   .....(ii)

now,

perimeter=2(l+b)=120cm

l+b=60cm            

from figure and using (ii)

[5x/2]+2x-3=60

[5x+4x-6]/2=60

9x-6=120

9x=126

x=126/9

x=14                                                                 ..........(iii)

substitute (iii) in (i)

y=14/2

y=7                                                                  ...........(iv)

From figure,

length=2x+y                                                   [using (iii) and (iv)]

=2x14+7

length=35cm

breadth=2x-3

=2x14-3                                                          ....[using(iii)]

=28-3

breadth=25cm

now,

Area=lxb

=35x25

=875cm^2
