Elena’s backyard is in the shape of a rectangle. she created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in. the area of the triangular flower bed is square feet. the area of her backyard that does not include the flower bed is square feet.

The complete question is as below and diagram is also attached:

Elena’s backyard is in the shape of a rectangle. She created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in. The area of the triangular flower bed is 125 square feet. The area of her backyard that does not include the flower bed is 575 square feet

The correct answer is 575 sq. m²

Step-by-step explanation:

The area of triangle = = = 125

The area of square = A = LW

                                = 35 × 20 = 700

Thus, the answer will be

= 700 - 125

= 525.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
